I'm looking for a nice spa holiday destination in Europe. Preferably in the south of France or Sardinia or Italy. As I can't walk too long and can't drive a car, I'd like to be able to cycle my way around country surroundings. I'm a solo woman traveller (36 yrs old) and I'm not necessarily looking for company, but also don't want to be in the kind of place where I'd stand out too much amongst romantic couples or families. Any advice?
